Understanding Computers and the Internet

Computer Science E-1

This course is all about understanding: understanding what's going on inside your computer when you flip on the switch, why tech support has you constantly rebooting your computer, how everything you do on the Internet can be watched by others, and how your computer can become infected with a worm just by being turned on. Designed for students who use computers and the Internet every day but don't fully understand how it all works, this course fills in the gaps. Through lectures on hardware, software, the Internet, multimedia, security, privacy, website development, programming, and more, this course "takes the hood off" of computers and the Internet so that students understand how it all works and why. Through discussions of current events, students are exposed also to the latest technologies.

Computer Science E-1 is a course at Harvard Extension School. E-1 isn't so much about computer science as it is about technology and how it all works. Most every student who takes this class uses computers every day but doesn't necessarily understand what's going on underneath the hood (or, in some cases, is outright scared!). All students exit this more comfortable with computers and the Internet.

Even if you are not a student at Harvard, you are welcome to "take" this course via computerscience1.tv by following along via the Internet. (The course's own website is at www.computerscience1.net.) Available at left are videos of lectures along with PDFs of problem sets. Sample solutions to the latter are not available, but if you have questions or would like to discuss the material with others, do join the course's Google Group.

If you're a teacher, you are welcome to adopt or adapt these materials for your own course, per the license.
